202 1 introduction of summer solar terms

As we all know, there are 24 solar terms in China, and the Great Summer is one of them, a very special solar term. How much do you know about the great summer? The following is the introduction of 202 1 summer solar terms for your reference. Let's have a look!

Introduction of summer solar terms

When the sun reaches longitude 120, it is a solar term of "great summer heat". "Great Summer", like "Little Summer", is a festival reflecting the degree of midsummer, and "Great Summer" means extremely hot. Twenty-four solar terms: "in mid-June, ... it was hot, small and small, small at the beginning of the month, and big in the month, and it is still hot now."

At this time, around "midsummer", most parts of the country will enter the hottest period of the year, and it is also the fastest growing period of warm-loving crops. However, natural disasters such as droughts, floods and typhoons frequently occur, and the tasks of drought, drainage, typhoon prevention and field management are very heavy.

Generally speaking, the summer solar term is the period with the most sunshine and the highest temperature in South China, the period with the most abundant rainfall, the most common thunderstorm and the most concentrated days of high temperature above 30℃ in western South China, and the period with the most frequent occurrence of high temperature above 35℃ in eastern South China.

The summer heat is also the season with the most thunderstorms. There is a saying that "the west can't walk without a drop of lightning in the east", which means that if there is lightning in the east in the summer afternoon, it won't rain here. If lightning is in the west, it will come soon, and it is too late to hide.

People often call the thunderstorm in summer afternoon "northwest rain" and describe it as "northwest rain, which falls on the driveway." "Summer Rain Over the Ridge" and "Summer Rain Over the Cow's Back" vividly illustrate that thunderstorms here are often sunny, just like the poem of Liu Yuxi, a poet in the Tang Dynasty: "The east is sunny and the west is rainy, but the road is sunny."

The ancient summer heat in China is divided into three periods: "The rotten grass in the first period is firefly; ; Second, wait for the soil to moisten and cool off the heat; It will be fine when it rains. " There are more than 2000 species of fireflies in the world, which are divided into aquatic and terrestrial species. Terrestrial fireflies lay eggs on hay, and when it is hot, fireflies ovulate, so the ancients thought fireflies were made of rotten grass. The second weather is that the weather becomes sultry and the land is wet. The third kind of weather is that there will be thunderstorms from time to time. This heavy rain will weaken the heat and humidity, and the weather will begin to transition to beginning of autumn.

Climatic characteristics of great summer heat

High temperature and extreme heat

Everyone knows that it is hot in dog days. Summer heat is generally in the middle of three volts. At this time, most parts of China are in the hottest stage of the year, and the temperature difference across the country is not big. Just in line with the proverb: "cold is in the March 9 th, and heat is in the middle." The summer heat is relatively mild, as the name implies, it is relatively hot.

Summer solar terms are in the "three volts", which is the period with the most sunshine and the highest temperature in China. Most parts of the country are dry and lack of rain, and the temperature in many areas is above 35 degrees, so the so-called "three stoves" are also the most prosperous.

From the middle and lower reaches of the Yangtze River to Jiangsu, Zhejiang, Jiangxi and other places north of South China, it is hot and rainy, and the rain drops like gold. There are some sayings, such as "Summer rain is as light as silver, and summer rain is as heavy as gold", "Rain in the rain, Ridomi hoards it", "Rain in rainy days, abundant grain and cotton", and "No drought, one acre plus one load".

As Heshui Zuo said in his poem, "The sun is shining and the weather is hot, but doing nothing and worrying about flies and mosquitoes. The cloud swells and the arrow scatters gold on the lotus pond. " If it rains around the summer heat, it indicates that there will be more rain in the future. There is a proverb in agriculture that "it rains in summer and water is enough in autumn;" It doesn't rain in summer, and I'm worried that I won't be able to eat water.

In the western part of South China, although the high temperature appears most frequently, the rain is the most abundant and the thunderstorm is the most common, which is the season with the most thunderstorms. There is a proverb here that says, "East flash can't go down, and west flash can't go." It means that in the summer afternoon, if there is lightning in the east, the rain will not come here. If lightning is in the west, the rain will come soon, and it's too late to hide.

According to whether it is hot or not, there are many agricultural proverbs to predict the weather in the later period: for example, in the short term, there will be a "great summer, and the fields will rest;" It is cool in summer and the pond is full of water "; Mid-term means "great heat, cool after autumn"; Long-term predictions include "the heat is unbearable, and there will be no frost for four months", "the heat is not hot, the winter is not cold" and "the heat is not hot, and the winter will rot".
